Reel or spool



R. V. OLSON REEL OR SPOOL Feb. 14, 1950 Filed Sept. 6, 1945 INVEN TOR ATTORNEYS Patented Feb. 14, 1950 REEL OR SPOOL Robert V. Olson, Attleboro, Mass., assigner to Mossberg Pressed Steel Corporation, a corporation of Massachusetts Application september 6, 1945, serial Natures' 6 Claims. (Cl. 242-123) This invention relates to a reel or spool of the type formed of sheet stock, and is an improvement on my construction illustrated in Patent No."2,258,580 dated October '1, 1941.

One of the objects of this invention is to provide a reel or spool which will be stronger than the reel or spool construction shown in the aboveentitled patent.

Another object of this invention is to provide al reel or spool which will have its center tube locked against circular moti'on with reference to the head or barrel.

Another object of this invention is to provide a reel or spool in which the head will be locked against axial movement as well as locked against circular movement.

Another` object of this invention is to provide a construction which will provide a secure lock between the center tube and the head or barrel without the use of welding, brazing, or the like.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described and particularly pointed outl in the appended claims.

In the accompanying drawings:

Fig. 1 is a fragmental sectional view of a reel or spool constructed in accordance with this invention;

Fig. 2 is an end view thereof;

Fig. 3 is a detail sectional view of a fragmental portion of the center tube and a portion of the head;

Fig. 4 is a fragmental sectional view of a modied structure.

In proceeding with this invention, I provide a head which has as a part of its construction an inturned center ange. The edge of this ange is notched and tapered on its side edges, While the center tube extends through the central opening about which the fiange borders and forms a margin and has raised from its stock lugs, which are also tapered and which are driven into the notches so that a secure tight t is provided between the side edges of the notches and the edges of the lugs. Thus, a secure rotary lock is' provided while, because of this tight t, an axial or longitudinal lock is also provided. The center tube is rolled over the head to lock the head against outward axial movement.

With reference to the drawings, I designates generally the barrel of the spool or reel and I'I designates generally the head. The head is composed of a plate I2 having an inturned flange I3 about its central opening and a rolled edge I4 forcing plate I5 and the plate I2.

barrel and is itself provided with a center opening I6 about which a ange I1 extends and projects inwardly, which flange is provided with al plurality of notches I8 in its edge I9. rThese notches are tapered or provided with converging side walls 20 as they proceed .away from the.

edge of the ange.

The barrel Ill abuts the flange I3 of the plate I2 and is welded thereto and reinforced by a member 2l which extends across the junction 22 of the barrel IIJ and the flange I3, all of these being welded together as at 23 to provide a firm joint. This member 2| has a flange extending outwardly as at 24 which fits between the rein- Member 2I also extends radially inwardly as at 25 and then axially as at 26 to engage a center tube 21 which extends centrally through the barrel I ll and through the opening I6 in the plate I5 of the head.

The center tube 21 is flared over the plate I5 as at 28 so as to firmly lock the center tube into position.

Lugs 30 are raised from the stock of the center tube 21 at a point inwardly from its end and these lugs are of a size to enter the notches I8. The lugs are tapered as at 29 so as to engage the side walls 20 of the notches I8 prior to the ends of the lugs engaging the bottom of the notch to be limited in its movement. In practice, the heads are forced onto the center tube 21 until the lugs are bent backwardly at their portions 3I so as to insure a tight fit between the lugs and the notches.

I find it preferable to taper the lugs and the notches in order to secure this tight fit, butin.

, some cases the lugs 3U' (see Fig. 4) instead of being tapered may be square as illustrated in Fig. 4, so long as some means is provided for causing a tight engagement between the sides of the lugs and the notches as well as some support to enable an axial thrust to be taken between the lugs and the notches.

Fig. 4 also illustrates a further modication inthat the member 2|' has no flange corresponding to the flange 24 as shown in Fig. 1 between the plates I2 and I5. In both Fig. 4 and Fig, l, however, the support provided from the portion 26 at the end of the radially extending portion 25 extends inwardly from the head so as to provide a central support for the center tube inwardly from the head, and thus a good bearing and reinforcement for the center tube nearer the center thereof than were this portion turned outwardly toward the end of the reel from the radial portion 25.

I claim:

1. In a reel or spool of 'sheet material comprising a tube, a lug spaced from the end of the tube and offset outwardly from the stock thereof, a, head having an opening through which the end of the tube extends, a flange on said head at the edge of the opening surrounding the tube, and a notch in the edge of the ange re'- ceiving said lug.

2. In a reel or spool as set forth in claim 1 wherein there are a plurality of. notches' and lugs spaced about the circular extent of the flange and tube.

3. In a reel or spool of sheet material, a head having an inwardly extending flange provided With a notch in the edge thereof, with its sides converging as they proceed away from the edge of the flange, an axially extending tube having a lug entering said notch and snugly engaging the sides thereof with its edges converging toward its free end, said lug being spaced from the end of the tube and oset from the stock thereof.

4. In a reel or spool as set forth in claim 3 wherein the end of the tube extends through 4 an opening in the head which said flange surrounds.

5. In a reel or spool as set forth in claim 4 wherein the end of the tube is flared over said head.

6. In a reel or spool of sheet material, a head having aninwardly extending ange provided with a notch in the edge thereof, with its sides converging as they proceed away from the edge of the flange, an axially extending tube having a lug entering said notch and snugly engaging the sides thereof with its edges converging toward its free end, said tube extending through said head and being flared over the head to hold the center of the head from moving out.
